[0039] Please refer to Figure 1-2 , an embodiment of the present application provides a wiping device capable of automatically replacing a wiping sponge 2, including an xyz-axis movement mechanism, a wiping head 1, a sponge automatic replacement part, and a wiping sponge 2. Among them, the wiping surface of the wiping head 1 adopts a curved surface structure. The wiping head 1 is mounted on the xyz-axis movement mechanism, and an adhesive layer is provided on the wiping surface of the wiping head 1; the wiping sponge 2 is adhered to the wiping surface of the wiping head 1 through the adhesive layer; the sponge automatic replacement part is arranged below the wiping head 1, and the sponge automatic replacement part is used to replace the wiping sponge 2 on the wiping head 1.

[0040] Specifically, the xyz-axis motion mechanism can be specifically composed of three sets of screw-slider mechanisms (the xyz-axis motion mechanism belongs to the prior art and is omitted in the drawings). The motion directions of the three sets of screw-slider mechanisms are perpendicular to each other. The xyz-axis motion mechanism is used to drive the wiping head 1 to move, so as to control the wiping head 1 to wipe or perform the action of replacing the wiping sponge 2. The wiping surface of the wiping head 1 can specifically be an arc-shaped structure.

[0041] By setting the wiping surface of the wiping head 1 into a curved surface structure, the local pressure of the edges and corners of the wiping sponge 2 on the surface to be wiped is avoided, and the surface to be wiped is protected. In addition, by controlling the movement of the wiping head 1 through the xyz-axis motion mechanism and cooperating with the sponge automatic replacement part, the automatic replacement of the wiping sponge 2 can be realized, solving the problem of great difficulty in the continuity of automatic wiping. There is no need to manually replace the wiping sponge 2, saving labor costs.

[0042] In one embodiment, the adhesive layer is a magic tape, and the wiping head 1 is connected to the wiping sponge 2 through the magic tape. The wiping sponge 2 is firmly adhered to the wiping surface of the wiping head 1 through the magic tape, ensuring the stable fit of the wiping material during the wiping process and avoiding the shedding or displacement of the wiping sponge 2. In addition, using the magic tape to connect the wiping sponge 2 and the wiping head 1 makes the replacement of the wiping sponge 2 simple and fast, reduces the maintenance cost, and improves the usability of the wiping device.

[0043] In one embodiment, the sponge automatic replacement part includes a sponge disassembly and assembly workbench 3 and a sponge continuous supply table 4. Among them, a sponge disassembly station 31 and a sponge compaction station 32 are provided on the sponge disassembly and assembly workbench 3; the sponge continuous supply table 4 is arranged on one side of the sponge disassembly and assembly workbench 3, and the sponge continuous supply table 4 is used for continuously supplying new wiping sponges 2.

[0044] When replacing the wiping sponge 2, first use the xyz-axis motion mechanism to move the wiping head 1 to the sponge disassembly and assembly workbench 3, and use the sponge disassembly and assembly workbench 3 to first remove the old wiping sponge 2 on the wiping head 1, so that the old wiping sponge 2 falls off the wiping head 1. Then use the xyz-axis motion mechanism to move the wiping head 1 to the supply station of the sponge continuous supply table 4 (that is, the position where the sponge stacking rack 43 close to the lifting mechanism 44 is located), use the xyz-axis motion mechanism to drive the wiping head 1 to press down, and use the adhesive layer on the wiping head 1 to adsorb a new wiping sponge 2. Then the xyz-axis motion mechanism controls the wiping head 1 to move to the sponge compaction station 32, and the xyz-axis motion mechanism controls the wiping head 1 to enter the sponge compaction station 32 to compact the wiping sponge 2, so that the wiping sponge 2 is more firmly connected to the wiping head 1.

[0045] In one embodiment, the sponge disassembly station 31 includes a disassembly channel 311 formed in the sponge disassembly and assembly workbench 3, and retractable disassembly teeth 312 disposed on both sides of the disassembly channel 311. The disassembly teeth 312 are driven by a piston device; a first infrared sensing device is further disposed in the disassembly channel 311, and the first infrared sensing device is electrically connected to the piston device.

[0046] When the wiping head 1 extends into the disassembly channel 311, the first infrared sensing device senses the extension of the wiping head 1, and then controls the movement of the piston device (specifically, a cylinder, etc.). The piston rod of the piston device extends, so that the disassembly teeth 312 on both sides move towards the middle of the disassembly channel 311 until the disassembly teeth 312 clamp and fix the wiping sponge 2 on the wiping head 1. At this time, the xyz-axis moving mechanism controls the wiping head 1 to move upward, so that the wiping head 1 is separated from the wiping sponge 2, and the disassembly process of the old wiping sponge 2 is completed. Then the piston rod of the piston device contracts, so that the disassembly teeth 312 retract to both sides, and the old wiping sponge 2 drops downward along the disassembly channel 311.

[0047] In one embodiment, an old sponge collection box 313 is disposed at the bottom of the disassembly channel 311, and the old sponge collection box 313 is installed on a trolley 314. By providing the old sponge collection box 313 at the bottom of the channel, it is convenient to centrally recycle the disassembled wiping sponge 2. In addition, by installing the old sponge collection box 313 on the trolley 314, it is convenient to transport the old wiping sponge 2.

[0048] In one embodiment, an arc-shaped groove consistent with the outer shape of the wiping head 1 is provided in the sponge compaction station 32. When it is necessary to compact the wiping sponge 2 to improve the connection stability between the wiping sponge 2 and the wiping head 1, only need to press the wiping head 1 into the arc-shaped groove to press the wiping sponge 2, so that the connection between the wiping sponge 2 and the adhesive layer on the wiping head 1 is more firm. And by setting the arc-shaped groove into a structure consistent with the outer shape of the wiping head 1, when the wiping sponge 2 is compacted, the wiping sponge 2 can better contact with each position on the wiping surface of the wiping head 1, improving the connection firmness between the wiping sponge 2 and the wiping head 1.

[0049] In one embodiment, the sponge continuous supply station 4 includes a base 41, a rotating mechanism 42, a plurality of sponge stacking racks 43 (specifically including a plurality of installed on the rotating platform), a lifting mechanism 44, and a second infrared sensing device 45. Among them, the rotating mechanism 42 is arranged on the base 41; the sponge stacking racks 43 are arranged around the rotating shaft of the rotating mechanism 42 along the rotating mechanism 42, and a plurality of new wiping sponges 2 are pre-placed on the sponge stacking racks 43; a lifting hole 421 is opened on the rotating mechanism 42 below the sponge stacking rack 43; the lifting mechanism 44 is arranged below the rotating mechanism 42, and the lifting mechanism 44 lifts the wiping sponge 2 in the sponge stacking rack 43 upward through the lifting hole 421; the second infrared sensing device 45 is arranged on the base 41, the second infrared sensing device 45 detects the height of the wiping sponge 2 at the top of the sponge stacking rack 43, and the second infrared sensing device 45 is electrically connected to the lifting mechanism 44.

[0050] Specifically, the rotating mechanism 42 includes a rotating platform and a rotating power part (specifically including a motor and a transmission device). The rotating platform is rotatably arranged on the base 41. The lifting hole 421 and the sponge stacking rack 43 are both arranged on the rotating platform. The rotating power part is fixed on the base 41, and the power output shaft of the rotating power part is connected to the rotating platform.

[0051] The lifting mechanism 44 includes a telescopic device (specifically, it can be a cylinder or a hydraulic cylinder, etc.) and a lifting piece (the shape of the lifting piece can be a sheet-like structure with an area smaller than the size of the lifting hole 421). The telescopic device is arranged on the base 41, and the lifting piece is installed on the telescopic rod of the telescopic device.

[0052] The sponge stacking rack 43 specifically includes a plurality of fixing pieces installed on the rotating platform. Each fixing piece encloses a three-dimensional space consistent with the shape of the wiping sponge 2, and the wiping sponges 2 are neatly stacked in the three-dimensional space enclosed by each fixing piece. Optionally, the bottom of the fixing piece is connected to the rotating platform, and the top of the fixing piece is provided with a bent head that expands outward. By setting the bent head, it is beneficial to add wiping sponges 2 into the sponge stacking rack 43.

[0053] When the wiper head 1 moves to the supply station of the sponge continuous supply table 4 (i.e., the position where the sponge stacking rack 43 near the lifting mechanism 44 is located), after the wiper head 1 descends a certain height, it adsorbs and takes away the top wiping sponge 2 in the sponge stacking rack 43 (the wiper head 1 descends to the height where its adhesive layer contacts the top wiping sponge 2). In order to facilitate the wiper head 1 to adsorb the new wiping sponge 2 when descending the same height during the next replacement of the wiping sponge 2, at this time, since the top wiping sponge 2 has been taken away, the second infrared sensing device 45 fails to sense the wiping sponge 2, and then the second infrared sensing device 45 controls the movement of the telescopic device in the lifting mechanism 44. The telescopic rod of the telescopic device extends, so that the lifting piece passes through the lifting hole 421 and pushes the wiping sponge 2 on the sponge stacking rack 43 upward until the second infrared sensing device 45 senses the wiping sponge 2 again. Then the second infrared sensing device 45 controls the lifting mechanism 44 to stop operating, so that the top wiping sponge 2 on the sponge stacking rack 43 rises to the initial height, facilitating the wiper head 1 to pick up the wiping sponge 2 next time.

[0054] When all the wiping sponges 2 on a certain sponge stacking rack 43 are used up (at this time, after the lifting mechanism 44 rises to the limit position, the second infrared sensing device 45 still fails to sense the wiping sponge 2, so it is judged that the sponge stacking rack 43 is empty), as Figure 5 shown. At this time, the second infrared sensing device 45 controls the operation of the rotating power part in the rotating mechanism 42, so that the rotating platform rotates a certain angle (the specific rotation angle is set according to the angular spacing between adjacent sponge stacking racks 43), so that the adjacent sponge stacking rack 43 is displaced directly above the lifting mechanism 44 (i.e., the supply station of the sponge continuous supply table 4) to continue supplying the wiping sponge 2, realizing the continuous and stable supply of the wiping sponge 2, so that the wiping device can continuously wipe.

[0055] In one embodiment, sponge continuous supply tables 4 are arranged on both sides of the sponge disassembly and assembly workbench 3. By arranging sponge continuous supply tables 4 on both sides of the sponge disassembly and assembly workbench 3, the automatic replacement times of the sponge automatic replacement part after being fully loaded with wiping sponges 2 are greatly increased, so that the wiping device can work continuously for a longer time without manual intervention (manually loading the wiping sponges 2 into the sponge stacking rack 43).

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
